A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves which ...
There are conflicting studies on the association between acoustic neuromas and cellular phone use and repeated exposure to loud noise. In 2011, an arm of the World Health Organization released a statement listing cell phone use as a low grade cancer risk. The Acoustic Neuroma Association recommends that cell phone users use a hands-free device.
Acoustic neuroma - a slow-growing, benign tumor of the acoustic nerve. [2] Symptoms, which most often start after the age of 30, can include dizziness, headache, vertigo, loss of balance, ringing sensations, and numbness. [3] Ganglioneuroma - a tumor of the sympathetic nerve fibers arising from neural crest cells. [4]
The review focused on studies of brain cancer and other cancers of the central nervous system—including glioma, meningioma, acoustic neuroma, pituitary tumors, and more.
Meningioma occurs in the membranes surrounding the brain and spinal cord and acoustic neuroma affects the nerve that connects the inner ear to the brain, according to the Mayo Clinic.
A common subtype is the vestibular schwannoma (acoustic neuroma). [5] Neurofibromas: Benign tumors that grow on nerves, commonly associated with neurofibromatosis type I (NF1). [2] Malignant peripheral nerve sheath tumors (MPNSTs): Rare but aggressive cancers that arise from peripheral nerves or nerve sheath cells. [6]
Schwannomas are relatively slow-growing. For reasons not yet understood, schwannomas are mostly benign and less than 1% become malignant, degenerating into a form of cancer known as neurofibrosarcoma. These masses are generally contained within a capsule, so surgical removal is often successful. [3]
Hardell's research on cell phones and cancer has concluded that long-term mobile phone use is associated with an increased risk of acoustic neuroma and glioma. [4] [5] He has said that children should be banned from using cell phones except in emergencies, as he feels the risk of cancer is greater in people who begin using mobile phones before the age of 20.
